Live blog and video of Volkswagen executive’s testimony to Congress

Follow along with MarketWatch reporter Rob Schroeder as he live-blogs the testimony by Volkswagen Group of America CEO Michael Horn to a House Energy and Commerce subcommittee. Officials from the Environmental Protection Agency are also testifying at the hearing, centering on the automaker’s emissions-cheating scandal.

VW is facing congressional scrutiny on several fronts. Sens. Orrin Hatch and Ron Wyden are demanding answers from the automaker over a federal tax-credit for fuel-efficient vehicles. Hatch is chairman of the Senate Finance Committee and Wyden is its top Democrat. They say that more than $50 million in credits may have been handed out to customers under false pretenses.

The German automaker has acknowledged it masked the emissions of new-car engines to sell clean-diesel technology in the U.S. market. VW has said as many as 11 million vehicles carried a so-called defeat device, or software that cuts tailpipe emissions when the car is being tested but not on the road.

The hearing’s now getting underway. Subcommittee chairman Tim Murphy says his first car was a VW beetle. But he’s quickly shifting into less-friendly territory, reeling off statistics about the cheating.
